Installation of a Zephyr (wall-mounted series) Wall-mounted heat pump in Vimont, Laval

Four-season comfort and impeccable finishing in a house in Vimont

At AirGreen , we have just completed the installation of a Zephyr wall-mounted heat pump in a single-family home in the Vimont district of Laval . The project showcases what many Greater Montreal homeowners are looking for: a discreet, energy-efficient HVAC system that is well-integrated into the interior design, installed using a rigorous and sustainable methodology.

Client background and objectives

Our client wanted to improve summer comfort on the ground floor, without sacrificing the visual harmony of the main room. She wanted a quiet unit, capable of providing additional heating during the off-season to reduce the use of the main system during thaws. The criteria chosen: energy efficiency , reduced noise level , precise temperature control and simplified maintenance .

Why the Zephyr wall series meets the need

The wall-mounted Zephyr is an excellent compromise for the typical living spaces of Vimont houses: medium volumes, light partitions and standard ceiling. The device combines a modulating fan , direct inverter expansion and stable control electronics, which results in:

• A uniform temperature and longer cycles, therefore fewer jolts .

• A front digital display allowing a quick reading of the set point (visible in the photo at 20°C ).

• A low interior noise level , pleasant for a living room or dining room.

• Controlled consumption thanks to continuous modulation of the external compressor.

When the home and electrical configuration are suitable, certain Zephyr versions can meet the efficiency standards required by provincial programs. We always work with our clients to verify actual eligibility (performance, certification, documentation) before submitting an application.

Interior installation: precision and optimal air diffusion

The interior head was positioned high on the wall , close to the ceiling, in order to:

• Maximize airflow range ,

• free up furniture space,

• and facilitate the return of hot air in air conditioning mode (as the hot air rises, the device benefits from better stratification).

The lateral positioning helps avoid obstacles (posts, wall returns) and directs the flow towards the most frequented living area. The motorized shutter naturally directs the air along the length of the room, reducing “dead zones”.

Connection management: a clean and reversible vertical chute

The connections (refrigerants, power supply, communication and condensate drain ) are routed in an ivory-colored vertical chute , from the bottom of the unit to the floor . This approach is ideal when the exit to the outside is at the bottom of the level or via a basement:

• Aesthetics : the pipes are completely concealed ; only the technical junctions remain accessible for maintenance.

• Performance : the insulation of the refrigerant lines is protected, limiting condensation and losses.

• Drainage : gravity drain is preferred, eliminating the need for a condensate pump (less maintenance and noise).

• Durability : the bending radius and the fixing of the pipes comply with the manufacturer's recommendations, avoiding any mechanical stress.

On the exterior (not shown), we adopt supports and UV capping adapted to the winter conditions of Greater Montreal (snow, freeze/thaw cycles, runoff water). The through-hole is sealed (fire-resistant foam/vapor barrier as appropriate) to preserve the building envelope.

AirGreen Installation Methodology: From Wall to Commissioning

Our teams follow a standardized procedure in accordance with RBQ requirements and good HVAC installation practices:

1. Structural verification and precise tracing of the mounting plate .

2. Calibrated drilling and installation of a sleeve to protect the connections.

3. Passage of pipes with butyl/insulating tape at critical interfaces.

4. Soldering/crimping according to the device technology, then nitrogen testing .

5. Deep vacuum (≤ 500 microns) and hold to validate the seal.

6. Fluid opening , superheat/subcooling checks and airflow verification.

7. Complete functional test : cool/heat modes, fan variation, remote control response and display calibration.

Each intervention is documented (measurements, photos, serial numbers if applicable) to facilitate future HVAC maintenance .

Interior finish: sobriety and integration

The careful finish is an AirGreen hallmark. Here, the vertical chute hugs the light-colored wall; the joining clips are compressed evenly, avoiding micro-gaps. The fixing screws are reduced to the bare visible minimum, and the service hatch remains accessible for the filters. The result: a discreet installation, which blends into the decor and makes cleaning easier.

Thermal result and comfort of use

Upon commissioning , the customer obtains:

• Quick cooling in summer thanks to the inverter soft start.

• A comfortable heating supplement in spring/fall to maintain a stable temperature without putting stress on the main system.

• Intuitive control by remote control; feedback (digital display at 20°C) provides reassurance about the active setting.

• Lower ambient noise compared to portable or window air conditioners.

AirGreen Operation and Maintenance Tips

To maintain performance and longevity:

• Filters : Vacuum/dusting every 4 to 8 weeks depending on use.

• Clearance : Allow at least 15 cm above/below the unit for air circulation.

• Condensates : confirm that the gravity flow remains free (no pinching in the chute).

• Outdoor unit : Maintain snow clearance in winter and defrost gently if there is accumulation.

• Annual visit : professional inspection (pressure switch, connections, exchangers, electronic parameters) — essential for maximum seasonal performance and durability .

Grants and administrative procedures

In Greater Montreal ( Montreal, Laval, Longueuil, North Shore, South Shore ), several programs evolve regularly. Eligibility depends on seasonal efficiency , low temperature performance and certifications of the installed device. We verify the criteria on a case-by-case basis (exact model, power, manufacturer's documentation) and can prepare the necessary supporting documents (detailed invoice, device numbers, installation photos). This assistance simplifies the process and secures the obtaining of aid when the device is eligible .

What this achievement says about our approach

• Adaptation to existing building: vertical trunking route to protect lines and keep the wall clean.

• Efficiency : Exemplary leak testing and vacuuming to prevent leaks and ensure performance.

• Aesthetics : discreet interior integration, harmonized covers , well-thought-out pipe routing.

• Support : usage advice, scheduled maintenance and monitoring for subsidies .

When to choose a wall-mounted Zephyr

We recommend the Zephyr wall mount when:

• The area to be treated corresponds to a single space (living room, open area, master bedroom).

• We are looking for an advantageous performance/price ratio with simple control .

• Expectations include immediate comfort , limited noise and minimal aesthetics .

For multiple needs (several rooms or floors), we offer MultiZone systems or central solutions (depending on the envelope and air distribution).

Conclusion

This installation in Vimont, Laval, illustrates the AirGreen signature: a clean, technically flawless HVAC installation designed for the long term . The Zephyr wall-mounted heat pump delivered here provides stable comfort in summer and off-season, while respecting the interior architecture of the house. Our team remains available for seasonal maintenance , optimization of settings and any possible expansion of the system if needs change.
